Jen Rubin applies Occam’s Razor:

I think those postulating a “McCain panic” theory to explain his campaign suspension don’t understand, or they pretend not to understand, John McCain. This is what he does. He elevates matters he considers higher national priorities above politics, which he finds at some level disasteful. Lots of people differ with his priorities, but that’s not at issue. If you look back over McCain’s career, he does this again and again: campaign finance reform, immigration reform, the surge and now this. He junks his party and the immediate short term political consequences when he thinks there’s something else at play. That in large part is what drive his GOP base nuts. And they likely won’t be thrilled here.

One can attribute nefarious motive ( “Ah! He’s just feigning love of country and putting his political career at risk!”) or you can take the more mundane explanation : this is how he operates and what he honestly believes. This performance with Katie Couric is plainly him at his best.

As for Barack Obama, I agree with this take that his initial effort to avoid involvement with brokering a deal didn’t come off all that well. (“It’s shocking that someone who believes himself ready to lead the free world would so brazenly try to dodge any participation in what could be a defining moment in our history.’) What was striking about Obama’s comment was his remark that if “the Congressional leadership” needed him, he’d be available. It’s an odd way to put it — he is the leader of his party now and he seemed utterly disinterested in doing anything that involved active problem-solving/deal-making. He does after all have a current job — in the Senate.

And this time, he’s not even voting “present.”

It’s a sterling example of his general career path–accomplishing little in his current job because he always views it as little more than a rung on the ladder to the next one.
